The improved doublehung window forming the subject matter of thepresentinvention comprises a frame orcasing 5 having weight compartments 6 andprovided with upper and lower sashes 1 and 8, saidsashesbeingmounted forvertical sliding movementwithin the casing'and so construct-' edastopermit the sashes to be swung inwardly to open osition when desired. 7

Secured to-the frame or casingi andextendg ing7 thefentire heightthereof, are outer hinge members 9, preferably formed. of sheetmetal andincluding angularly disposed portions llland 7| l.- the metal atthe endsof said portions being 'c'urled' or rolled to formtubular members or.sleevesflz and l3.7 One oflthese-hinge members is secured to each sideof the casingby screws or similar fastening devices- I4, with .the.portion.

Extendingthrough the interen gaging sleeves and operatively connected with the'upper and lower isashes, are windowc'ordsview "of the 1 22 which extendoverisuitable pulleys 23 mounted in the frame and thence downwardlywithin the compartment- 6 for attachment to suitable weights 24. Thesleeves [3 of the outer hinge members 9 are offset with respect to thesleeves I2 thereof so as to permit the upper sash to be swung inwardlyto open position without interfering with the lower sash, the rear edgeof the upper sash being cut away at 25 to permit swinging movementrofthe upper sash without binding shownin Figures ,9 to 12 inclusive of thedrawings. This assembly-comprises a vertically disposed substantiallyU-shaped member or strip 26 extending the entire height. of eachsashiand provided with laterally extending flanges 2'l,jthe

portion 26, being adaptedto 'fit'within a seating 3 groove 28 formedinthe adjacent face of the win a terminal angularlip 30' which coac'tswith" a I cam 3| for the purpose of. releasing the U-shaped 1 .inember26 from within. the groove 28 when it is desired toswingthe'jadjacentfsash'inwardly, as will be morefully explainedhereinafter.fEach seated in eachjreces s is a fmetal casing 33 havingoutwardly bowed springs 3 attached thereto and 1 which serve to normallyand .yieldably hold the 3 sash is providedwith a longitudinal recess32and member 26 within the seatinsj roove so asto insure a weather-tightjoint between the parts.

When; the member '26 is in extended position, 1 the flanges ,21Iwillbear .against, the adjacent portionof the casing33 and limit the inwardmovement of said member. Two 3| are preferably'provided for each windowsash, each cam being secured'to a stub. shaft 34' journaled I in theadjacent window sash, and each stub shaft i being provided with'aterminal slot35 adapted to 1 receive a suitable tool for turning thecam. EX-

- tending laterally from each recess 32 and com- 3 municating therewith,is an auxiliary. recess: 36 3 which serves to receive the adjacent cam3| and cause the U-shaped members or strips 26 to seat within theadjacent grooves 28 and thereby holdthe sashes against'swinging movementand,

I for swinging movement, it will be understood ,do'w frame." Extending,laterally from one side of each Ueshaped member 26 is an arm 29 havingat the same time, insure a weather-tight contact 7 between the parts.While both sashes may be slid vertically at any time and each is,mounted that theinner sash must be swung inwardly to thepositionindicated by dotted lines of Figures 3 and '5 beforethe oute'n's'ash 1canbe swung inwardly to the position shown in Figure 5.

The construction of the'sleeve hinge members and their attachment to thesashes is such that either sash may be swung inwardly to open position'so that the window may be used'in the same manner as'an inwardlyswinging casement window. If desired, a suitable packing 3% may beseated in the window frame and the'groove 28' formed in said packing inorder to assist in providing a weather-tight connection.

3 In Figure'laofthe drawings, there isillustratedamodifie'dfmm of theinvention designed to reinforce "and strengthen the side stiles of thesashes. .Inthis form ofthe device, onefof the vertical stiles of eachsash is reinforced and strengthened by theprovision of a metallic casing3'l1and'slidably mounted withinsaid casing is a hollow actuating member'38 which-receives the cam 39, said actuating member being provided withterminal hook'portions Mlada'pted to engage suitable-lips 4| carried bythe U-shapdmember or strip42, there being bowed springs s31; disposedwithin the. casing 37' for causing the U-shaped stri 42 to yieldablyengage the groove in'the casing when the cam 39 is moved to re 3 leasedposition. In this form of the device, when thecam-is rotated, the hooks.40, by engagement I with the lips 41, will retract the U-shaped'stripto'permit longitudinal movement of 'the arm 29 I whenthe cam .isrotated.

It will thus .be seen that, underordinaryv con T ditions, the upper andlower sashes. maybe ad- 'justed vertically of the window fr'ame'to anyde 3 sired position and in which event the sleeve hinges act as guides,itbeing understood, of

course, that there will be sufficient clearance be- I tweentheU-shapedmemberlfiand the groove 2a to permit vertical slidinginovementof the sashes while, at the same time, insuring a good 3 weather-tightcontact with the window frame. 1 When it is desired to swing either theupper or lower sash inwardly to open position, a suitable tool isinserted. in 17116 slot-35- of the adjacent stub shaft 34 and the cam3lcarried thereby rotated soas to retract the ,u-shaped member 1against'the. tension of the bowed springs 34 and 5 thus release saidU-shaped member from the v groove'28 so that either-sash is'free'toswing 1 laterally to. open position withv the sleeve hinges 1 Ias pivots.

verse direction, the Springs 34 will automatically By rotating the cams3| in the re- 42 against the tension ofjthe springs 43 and,

3340 when the cam is moved to released position, the

springs '43'will cause the strip '42 to automatically-'seat within theroove in the casing, as will bereadily understood; While the sleevehinge 'm'ounting'and weather strip assembly is particularly designed foruse on windows of wood construction, it will, of course;

be understood 'thatthe'device maybe usedwith equallygood results on ametal window. It will also'be understood'that thedevice may be made in'different sizes and shapes and constructed of any suitable materialwithout departing from .the spiritof the invention.
